Thorn History Mansion, cross-courtyard small building.

Wu Conghan walked briskly, and as soon as he entered the courtyard, he smelled a pungent stench, and immediately covered his nose with his sleeves, and asked the servant who was leading the way beside him, "What is this doing?" Why don't you clean up this place! ”

The servant said with a bitter face: "Wu participates in Mo Wei, this is the Lord is developing fertilizer, I am not allowed to wait in to clean it, it has been several days, if it weren't for the wind in the past two days, it is estimated that most of the Thorn Mansion would be stinking!" ”

Wu Conghan was dumbfounded.

Entering the courtyard, Wu Conghan directly followed the smell to find Li Congyan, only to see that Li Congyan was wearing a short shirt at this time, although the weather was still very cold, but Li Congyan was sweating profusely, and he had obviously been busy here for a long time.

"I've seen the Lord!"

Li Congyan beckoned to Wu Conghan with a smile, and then said, "Come and see these, they are all fertilizers developed by me personally." With these new fertilizers, the yield per mu of the people's autumn harvest can be increased by at least one to two percent! ”

Wu Conghan was very surprised when he heard this, and he didn't care about the pungent smell at this time, and squatted down to carefully observe the fertilizer spread on the ground.

"Lord, what kind of fertilizer is this, could it be the farm manure and plant ash?" Wu Conghan said thoughtfully.

"Hmmm......"

Li Congyan thought for a moment and said, "This new fertilizer is called chemical fertilizer." ”

"Fertilizer? What is Fertilizer? Wu Conghan was still full of doubts.

Chemical fertilizers, also known as inorganic fertilizers, include nitrogen fertilizers, phosphate fertilizers, potassium fertilizers, micro fertilizers, compound fertilizers, etc. But Li Congyan couldn't explain it like this, and he couldn't explain it clearly with Wu Conghan, so he said: "How to make this fertilizer, I will summarize a set of methods, you just need to know that the effect of this fertilizer is many times stronger than farm fertilizer and plant ash, not only can improve the yield of grain, but also for the crops in the field are very applicable, the land with chemical fertilizer can reach two crops a year in the south, and the output will not decrease, but will increase a lot." ”

After Li Congyan finished speaking, Wu Conghan's expression changed from confusion to shock, is there still this magical fertilizer in the world?

Since the introduction of the Land Decree, Li Congyan has temporarily turned her attention to farming. In this era when most people have enough to eat, hundreds of people are struggling to survive with food and clothing, and even some rich families will starve to death for various reasons.

Li Congyan thought about it for a few days, and then decided to start with fertilizer and farm tools, and do his best to increase the yield per mu of the people of Dengzhou; if the implementation is successful, it will not only make the people of Dengzhou have enough food and clothing, but also accumulate a large amount of military rations for themselves, and greatly improve the strength of Dengzhou.

Li Congyan tinkered in the Thorn History Mansion for a few days, because there is no industrial sulfuric acid in Dengzhou now, and now Li Congyan does not have the basis for making industrial sulfuric acid, so there is no way to make modern fertilizer, so he came up with this manufacturing method of soil fertilizer.

As for the soil method of making fertilizer, Li Congyan also knows several kinds, before coming to this era, Li Congyan was still working in his hometown, and at that time, in order to save money, he even made his own fertilizer.

Wu Conghan observed and asked, "Lord, how is this, chemical fertilizer, how is it made, and it has such a great effect?" ”

Li Congyan kept turning over the fertilizer on the ground with the rake in his hand, and said: "This fertilizer is made of 100 catties of fresh livestock manure, with one or two of soybean flour and 10 catties of cooked gypsum powder.

This is the soil ammonia water used to make homemade soil fertilizer, and it is a low-cost and efficient fertilizer even in the next generation.

Wu Conghan suddenly realized: "No wonder the lord asked me to prepare a few days ago, dug dozens of cellars according to the drawings given by the lord, and specially demarcated a wasteland in the south of the city, which turned out to be the place where large-scale fertilizer production was prepared!" ”

Li Congyan said with a smile: "Although this kind of fertilizer is simple to make, the soybean flour and cooked gypsum powder required are not available to ordinary people, so it also needs to be led by the Thorn Shifu to manufacture it, and then promote it throughout Dengzhou." ”

Wu Conghan frowned slightly, and said: "It's okay to say that this livestock manure, most of the people around the country raise all kinds of livestock, and it's good to find a way to collect it when the time comes." Just how to collect bean flour and cooked gypsum powder in large quantities? ”

"That's easy!"

Li Congyan said: "The day before yesterday, I had already contacted the Li family in Penglai and the Chen family in Huangxian County, asking them to prepare money and grain to build their own gypsum factories to supply plaster powder for the fertilizer workshop that was about to be built. ”

"What about soy flour and livestock manure?"

"In the case of soybean flour, it is not cost-effective to build a special workshop, and it will also increase the price of chemical fertilizer products, which is not conducive to the promotion of chemical fertilizers, which is a difficult point."

Li Congyan seemed to be a little tired, clapped his hands and beckoned Wu Conghan to find a place to sit down, and then said: "So I came up with this method: first let the Thorn Shifu find a way to get a batch of livestock manure and soybean flour, and Mr. will produce a batch of chemical fertilizer for promotion." When people everywhere see the efficacy of chemical fertilizers, they will definitely flock to it. At that time, the Thorn History Mansion will post an announcement: the people are allowed to exchange livestock manure and soybean flour for finished fertilizer, and the specific exchange amount will be measured in detail. ”

"In this way, there is no need to worry about the poverty of the people who cannot afford to use chemical fertilizer, and the fertilizer workshop no longer has to worry about the shortage of raw materials."

Wu Conghan clapped his hands after hearing this, but then asked: "But in this way, wouldn't the fertilizer workshop lose money and make money?" After all, plaster powder needs to be purchased, and the craftsmen and manpower in the workshop also need to spend money, so you can't just sell a copy, right? ”

"Who says it's not for sale?"

Li Congyan had already thought of a way and said: "In the future, the supply of these fertilizers to the people is only a part, and the purpose is to increase the yield per mu of the people and increase the tax revenue of the Thorn Mansion." A large part of the fertilizer will be sold to those families and merchants! ”

"Although there are not many families left in my Dengzhou, and there is not much arable land in the hands of those merchants, there are so many families and businessmen in the world, and the arable land in their hands is countless, and they can sell chemical fertilizers to the outside world in the future, and they will definitely make a lot of money!"

Speaking of this, Li Congyan said to Wu Conghan: "The gypsum factories of the Li family and the Chen family can be completed in about a month, and they have also contacted the gypsum mine, and the output will be available in two months at most." Therefore, the fertilizer workshop in the Assassin Mansion was to be completed within a month, and then the local government offices were ordered to contact the people and use the money to buy a batch of soybean flour and livestock manure. As for the later promotion, you are responsible for it. ”

Wu Conghan forked his hand and promised.

Then, Wu Conghan took out a list and presented it to Li Congyan, saying, "Lord, this is the address of the woodmills in various places in Dengzhou, as well as the list of carpenters on record. A few days ago, the Lord wanted to collect this information, and now it has been registered, so please take a look at it. ”

"Good!"

"I just don't know what the Lord wants this information for?"

Wu Conghan secretly said in his heart: "Does the Lord still want to build a woodcraft workshop?" ”

Li Congyan pulled Wu Conghan to the other side of the courtyard, pointed to a few things on the ground with strange shapes, and said, "I want to gather the carpenters of Dengzhou to build these things on a large scale!" ”

"This、This is the Koto plow?"

Wu Conghan looked at several alien Jiangdong plows on the ground in surprise, and said secretly: "Do you really want to build a woodcraft workshop?" ”

Li Congyan ignored Wu Conghan's surprise, but said: "Its Yuanqu, because of its name, is called Quyuan Plough and is different from Zhiyuan Plough. Because it was first popularized and applied in Suzhou and other places, it is also known as Jiangdong plow. ”

"There are several major improvements over the previous plough. First of all, the straight wheel, the long wheel is changed to the curved wheel, the short wheel, and the plow disc that can rotate freely is installed at the head of the wheel, so that not only the plow frame becomes smaller and lighter, but also is convenient for turning and turning. ”

Li Congyan said that these are the advantages of the Quyuan plow, and the disadvantage of this plow is also obvious, that is, it cannot be deeply cultivated.

Especially in the relatively hard cultivated land like Dengzhou, if you can't dig deeply, the seeds can't be buried in the moister deep soil, so even if you have good fertilizer, it won't help, and the yield of crops is not destined to be high!

After explaining the advantages and disadvantages of the Quyuan plow to Wu Conghan, Li Congyan explained to an improved Quyuan plow.

It turned out that Li Congyan's improved version of the curved plough had been greatly modified, first making a part like a plow rake, consisting of three medium-length logs, one round and the other pointed, fixed together by a small frame.

Then a trapezoidal wooden frame was made with a few wooden boards, but the bottom surface of this trapezoidal wooden frame was not sealed, and the bottom surface of the unsealed wooden frame was open upwards like a trumpet. Then a chisel was used to drill a small hole under the trapezoidal wooden frame, just enough to accommodate the seeds to pass through. The next step was to make two longer straight sticks out of timber, connect the two parts, and combine the trapezoidal frame with the part that resembles a rake.

In fact, the improved Quyuan plough designed by Li Congyan is scientifically called cocoon, which is a kind of agricultural tool that can both plough land and sow seeds.

This kind of cocoon is pulled by livestock and supported by someone behind it, and can complete both ditching and sowing at the same time. Plant one or more ridges at a time, and up to five ridges. To put it bluntly, it is an ancient seeding machine, which is used to sow seeds, also known as "plows", and is also called a plow.

If Li Congyan remembers correctly, in fact, at this time, cocoon has already appeared, but because the imperial court did not vigorously promote it, and various reasons such as the festivals in various places made their own affairs, it was not popularized, and Wu Conghan naturally did not see it. Because of this, Li Congyan named this kind of cocoon plough as the new Quyuan plough for popularization.

After listening to Li Congyan's explanation, Wu Conghan was excited, and said loudly: "The Lord is really a Wenqu star, and he can create such an artifact!" With this thing, the people of Dengzhou only need two to three years to be able to have enough food and clothing, as long as it is not a natural disaster for many years, they can naturally live and work in peace and contentment! ”

"It's just, I don't know how much this new Quyuan plow costs?"

Wu Conghan is still worried about the cost, worried that ordinary people can't afford to use it. Even looking at the materials and ingenuity of the new Quyuan plow, it is quite difficult for ordinary people to build it themselves, and it is not at all something that ordinary people can use.

Li Congyan has already calculated, and ordinary farmers naturally can't afford to use it, so they have already thought of countermeasures.

"The Assassin's Mansion first set up a woodware factory, and then promoted the new Quyuan plough to the people of Dengzhou at cost price, and allowed the people to pay in installments for 20 years, and they could pay with grain!"

Speaking of this, Li Congyan laughed and said: "Of course, the wood factory also needs to face other states and counties, as for the price of external sales, on the basis of the cost price, plus thirty percent of the profit, and those who order less than ten will have to pay for the freight!" ”

Wu Conghan laughed when he heard this, and said: "My subordinates understand, this price is naturally also aimed at the families and official and business families in other states and counties. ”

"Needless to say!"

Li Congyan asked with a smile: "Do you have any suggestions for the person in charge of the fertilizer workshop and the woodware workshop?" ”

These two workshops were both built by the Assassin's Mansion, and they were workshops that could bring great benefits to the Assassin's Mansion, and in Li Congyan's opinion, they must be run by reliable people.

Wu Conghan thought for a while, and then said: "My subordinates think that Wang Hao, the deputy of Si Cang of the Assassin Mansion, and Guo Mingsi, who joined the army, can be competent. These two are the old men of the Assassin's Mansion, and they are very good at farming and equipment. Moreover, these two people have moderate abilities, when Liu Yu and others were in power, the two were snubbed because they were ashamed to be with them, and they could be trusted in terms of character. ”

"Okay, it's just the two of them. With Wang Hao as the head of the wood workshop and Guo Siming as the head of the fertilizer workshop, the two of them were ordered to be fully responsible for the preparation and promotion! ”

"Whoa!"
